So the real question becomes, do we want them using browsers like OpenAI’s new browser, that will likely mine everything they do for their datasets?

What is the difference?

Or do we want a browser that can limit what these AIs can scrape up, like Firefox?

Where has Mozilla shown that Firefox in any way limits what is scraped? All I see is jawboning.

We need to build alternatives that aren’t controlled by billionaires, massive corporations, and venture capitalists.

Okay. Who is doing it? Not Mozilla, clearly.

But if I have to choose between them, I’d rather back Mozilla.

Why? They are using stolen data to obviate community contributions. Your trust seems misplaced.
